Statistical Summary of the Models.

Median models across MaxEnt replicates were evaluated using the area under the receiver operating characteristic curve (AUC), the SD of the AUC across replicates, and the proportion of the potential distribution model with an SD of the replicates >0.15





Definitions of Conservation Scores

Sampling Representativeness Score (SRS)

*Insitu : The sampling representativeness score in situ (SRSin) calculates the proportion of all occurrences of a taxon within its native range that fall within a protected area.

Exsitu : The sampling representativeness score ex situ (SRSex) calculates the ratio of germplasm accessions (G) available in ex situ repositories to reference (H) records for each taxon, making use of all compiled records irrespective of whether they include coordinates.

Geographic Representativeness Score (GRS)

Insitu : The GRSin compares the area (in km2) of the distribution model located within protected areas versus the total area of the model.

Exsitu : The GRSex uses 50-km-radius buffers created around each G collection coordinate point to estimate geographic areas already well collected within the distribution models of each taxon and then calculates the proportion of the distribution model covered by these buffers.

Ecological Representativeness Score (ERS)

Insitu : The ERSin calculates the proportion of ecoregions encompassed within the range of the taxon located inside protected areas to the ecoregions encompassed within the total area of the distribution model

Exsitu : The ERSex calculates the proportion of terrestrial ecoregions (25) represented within the G buffered areas out of the total number of ecoregions occupied by the distribution model.

Final Representativeness Score (FCS)

Insitu : The FCSin was derived by calculating the average of the three in situ conservation metrics.

Exsitu : The FCSex was derived by calculating the average of the three ex situ conservation metrics.

FCSc-mean : The FCSc-mean was calculated for each taxon by averaging its final FCSex and FCSin scores. Taxa were then categorized with regard to the two conservation strategies as well as in combination, with UP for further conservation action assigned when FCS <25, HP assigned when 25 ≤ FCS < 50, MP when 50 ≤ FCS < 75, and LP when FCS ≥75.

Definition of Occurrence Data Categories

Observations : The total number of records for the species that were evaluated for used within the study.

Observations with lat/long: The total number of records that had a valid latitude and longitude pair and were used for spatial analysis. Non valid latitude longitude pairs included but is not limited to; points not over land masses and records with only one of the two values present.

Germplasma Records(G) : Observations in which a living sample (via plant or seed) is present in a preservation focused environment (botanical garden, seed bank). These are observations which could protentially produce viable genetic resource information and are therefore evaluated with the suite of exsit focused conservation metrics.

Herbarium Records(H) : Observations that have a supporting herbarium record.

Unique Data Sources: The number of unique data base sources from which observations of the species were gathered.

  1. Select Expected Habitat

  2. Select Buffer Germplasm Collections

    The green area outside of the purple is expected habitat that is more then 50km from a germplasm collection. These are potential gaps in the collection of this species.
